Product details
The supplied gear oil (3 quarts) exceeds the performance requirements of API GL-5 recommended for both open and limited slip applications. This cover has an increased oil capacity over stock for better performance over a longer duration. Built-in internal and external fins transfer heat from the oil to the outside air for maximum cooling. This cover incorporates a magnetic drain and deep reach fill plug to capture loose particles for maximum protection. A calibration plug is set to the factory oil level to prevent overfilling. A pre-installed oil level sight glass allows quick and easy oil inspection.
